The name of the powerful and illustrious king of Khadgi town
in Purva Mahavideh area was Simhavaha. He was a very devoted and
religious person when his son became young and capable, he handed
over his kingdom to the son and took Diksha from Samvaracharya.
As a result of his vigorous penance and devotion for the Arhat,
he earned the Tirthankar-nam-and gotra-karma. Completing his age
he reincarnated in the Sarvarthsiddha dimension of gods.

From the dimension of gods he descended into the womb of queen
Shri Devi, wife of king Shursen of Hastinapur. During her
pregnancy the queen saw a heap of gemstones known as Kunthu in
her dreams. This inspired the king to name him Kunthu Kumar. The
pious deeds of earlier birth resulted in unlimited power and
grandeur for Kunthu Kumar. After Shursen became an ascetic,
Kunthu Kumar ascended the throne. Soon the disc weapon appeared
in his armory and he proceeded to conquer the world with his
mighty army. Without any confrontation all the kings accepted his
sovereignty and Kunthunath became a Chakravarti. Many mighty
kings and princes used to be present in his court all the time.
After a long and peaceful reign of twenty three thousand seven
hundred and fifty years he became an ascetic along with one
thousand kings immediately after Diksha he acquired Manahparyav
Jnan. He spent sixteen years as an ordinary ascetic. Indulging in
penances and other spiritual practices, he attained omniscience
on the third day of the bright half of the month of Chaitra under
a Tilak tree in Sahasramara jungle outside Hastinapur. His first
discourse was on the subject of "inner purity".

As an omniscient ascetic Kunthunath wandered around and
preached true religion for a very long period. He then went to
Sammetshikhar and observed a month long fast before breathing his
last. His followers were deeply devoted to him. As such, a large
crowd was present at the moment of his Nirvana and cremation
ceremony. They witnessed the ceremony with heavy hearts and tear
filled eyes. The mortal remains of Bhagavan Kunthunath were taken
away by the gods for worship.
